Internal validity refers to the extent to which a study can ensure that the independent variable is the only factor influencing the dependent variable. In other words, it measures whether the observed changes in the dependent variable can be attributed to the manipulation of the independent variable. Therefore, having internal validity is crucial for making valid inferences about the effect of the independent variable on the dependent variable. External validity refers to the extent to which the results of a study can be generalized to other populations or settings. Sample validity and inferential validity are not relevant to this question.
